In 'The Dark Knight', Batman (Christian Bale) faces his most dangerous adversary yet, the Joker (Heath Ledger). Amid a rising tide of crime and corruption, Batman must use every tool at his disposal to save Gotham City from the Joker's reign of terror.
A bank robbery. The Joker’s subordinates kill each other one by one until only the Joker remains. The opening is exactly the film’s philosophy in miniature: chaos as systematic, not random. Nolan shot it on IMAX so the geometry would hit harder.
The Joker proposes that order is a fragile lie maintained by people pretending not to notice. Batman wins the fight, technically, but the Joker wins the argument: Gotham’s most "honest" hero ends the film accepting blame for murders he didn’t commit, exactly as the Joker predicted.
The Joker's chaos theology—civilization is one bad day from collapse—gets explicitly refuted by Dent's coin and Batman's final act. And yet, the film keeps proving him right in every frame.
